Yeah well as I can see, D3 influence parameter will control the
interpolation between the normal from the normal map and the normal from the
original surface (or you can pass it another normal map in the normal input
and it would use that one instead of the original surface normal to
calculate the interpolation)... so yes, there is an amplitude parameter in
D3.

That makes sense Raffaele but the D3 nromal shader does provide an influence
parameter that does appear to work pretty much the way a bump map amplitude
works.

amplitude on a normal map?
after the relief/displacement derived normals have been calculated, or if
you're using a straight baked normals map (derivated from the difference
between geometries, like in Zbrush), you don't have an "amplitude" anymore.
an amplitude is only possible when setting a height for a relief mapping of
some sorts, once the normals are derivated there's no amplitude you can set
for them.
I don't remember D3 having an amplitude parameter and I can't see how it
could have had one, but then I haven't used it in ages and I'm maybe missing
something.

Yes the XSI native normal map nodes seem to be lacking somewhat. I
also noticed that there is no control for amplitude either.
You'd think they woudl have though of these paramters when creating
them, seeing as they already existed in D3.

Hey list -
Maybe I'm missing something, but there doesn't seem to be a way to set
the repeats for a normal map texture. I don't see a way of setting the
repeats anywhere in the XSI Normal Map Node - even if you click on
Edit, it brings another PPG to mess with the UVW Transformation, the
Wrapping, even the Swap UV - but no repeats ??
Anyway I'm using the D3 Node instead for the time being but
nonetheless I'm still curious as to why we can't set the repeats... Anyone
?
